I can't do an apples-to-apples comparison on the ROI because obviously, they're different markets - but they're all in the same ballpark.  

I keep my rentals in Buffalo NY, where the property values and taxes are low and the rents are high in comparison, as I imagine is the case in Erie. 

Here is a side by side comparison of the owner statement I got (on top) and the ledger she kept (bottom). 

Well here are few that I can think of:- You are an Accountant - who views the reports once a year to do taxes (That is it)- You are a Bookkeeper - you want to do the data entry because it does not make you money- You are a DIY QuickBooks user - who will surf the internet and YouTube for answers and not have the full process, procedure, and solution- You are a CFO - review your financials every day or week, depending on your business goalsNow let's get into the nitty-gritty:- You as a business owner should look at your reports by each property and unit- You should compare your Profit and Loss by:----- Month----- Quarter----- Year----- Previous Year Comparison----- By % of your Income ----- and the list goes onNow about your Equity - view your Balance Sheet and see the difference from previous year how much money you paid and received by improvements and loan, the personal money you invested and more...If you are looking at keeping the books for tax purposes and IRS, as well as use paper and pencil.

Some benefits are that the loan can cover much higher loan amounts in comparison to an FHA loan which may have county limits, among other things. 

Depending on fluctuations in your market, it is a lot easier to owe more than your house is worth when you are putting 3.5% down in comparison to the 20% down on conventional loans.  

If I were to rent it, based on comparisons I believe that I could get approx $1600 per month, minus the $1455 ($100 renting fee, and the $1355), I would be making $145 per month.

You can install it in basements below grade, etc, due to it's minimal expansion and contraction (in comparison to other wood).  

An apples to apples comparison should include the park price.  

Hi Javier, I think the ultimate best way to save your money is to add a knowledgeable and proactive accountant into your team.The wholesalers are taxed very aggressively in comparison to landlords, but a couple of things that just popped in my head:- consider living/investing in a state with no state income tax- consider investing through tax-deferred plans like IRA- consider creating a corporation and make sure you maximize your tax deductions
